Metal material composite electrodeposition diamond grinding pad and manufacturing method thereof

Abstract

The invention provides a metal material composite electrodeposition diamond grinding pad. One or more than one metal and diamond are electronically deposited on a flexible conductive matrix together in an electroplating mode, and a metal-diamond composite layer is formed on the matrix. The metal or alloy which wraps the diamond is fixed on the matrix, so that a grinding function is fulfilled; a loop surface or a hook surface of a hook-and-loop tape is adhered to the other surface of the matrix by an adhesive, so that the matrix can be connected with corresponding using equipment conveniently. According to the metal material composite electrodeposition diamond grinding pad, a metal material is used as a binding agent and replaces a high polymer material binding agent, strength, wear resistance, heat resistance and heat dissipation performance of the binder are improved, the grinding temperature is directly reduced, deadly defects such as high polymer material burning and dyeing are overcome, the metal material composite electrodeposition diamond grinding pad not only can be used for water grinding, but also can be used for dry grinding, meanwhile, the service life of the grinding pad can be greatly prolonged, and the grinding efficiency is greatly improved.

Description

technical field [0001] The invention relates to a metal material composite electrodeposited diamond grinding disc and a manufacturing method thereof. Background technique [0002] Non-metallic materials are more and more widely used in production and life, such as from cement floor to granite, marble, ceramic floor tiles, glass, silicon wafers, and the emergence of sapphire mobile phone panels. The requirements for processing quality in many fields are getting higher and higher, so the demand for grinding and polishing tools is increasing, and the grinding performance is getting higher and higher. Initially, diamond grinding discs used polymer materials as a binder. Due to the poor heat resistance of polymer materials, water must be added to cool them during grinding. This is the so-called water grinding disc. Due to the limitations of the processed material and the processing environment, many grinding processes are not suitable for cooling with coolant, and dry grinding a...

Problems solved by technology

[0005] The patent application with the notification number CN101722478A discloses a diamond dry grinding disc and its manufacturing method. The abrasive layer of the dry grinding disc is made of a mixture of high temperature resistant resin, diamond particles and wear-resistant and heat-dissipating additives. The wear-resistant and heat-resistant material additive improves the heat resistance of the resin in the abrasive layer, and the process is improved. It is molded by first closing the mold, hot pressing, and then curing, and can be made into a thicker dry abrasive sheet. Although the temperature resistance of diamond dry grinding discs has been improved, it also cannot completely change the heat resistance of the polymer material binder itself, nor does it reduce the grinding temperature.

In addition, the molding method of mold closing and hot pressing has high requirements on equipment power and heat, which is not conducive to energy saving; volatile organic compounds are produced during the production process, which is not conducive to environmental protection
